I spent quite a few hours working on this question, because I'm a firm believer in RTFM.I abandoned the "tracker" properties because they seemed to be the 8 shapes that appear when I select a shape.A Google search fornevron diagram selected shape style

does not return any results that lead to the answer.I realize that search visibility is difficult. I understand that "RubberBandStrokeStyle" is its name, but no way for me to know that if I didn't know that the thing I was seeing is a static rubber band. I clicked the shape once to select it, so I wasn't thinking "rubber band". If I had dragged to select it, I might have associated that concept with the style.
